二十世纪七十年代在对铁器进行保护修复时，国家博物馆文物保护修复人员根据器物的锈蚀程度对器物进行了清洗、除锈、脱盐、粘接、封护等处理。时隔四十多年，再次审视和查看当年保护修复过的四件铁器时，为了更科学地了解当时使用的保护修复材料的现状，本工作采用傅里叶变换显微红外光谱(Micro-FTIR)和热裂解气相色谱-质谱(Py-GC/MS)分析了铁器上的保护修复材料：粘接剂和封护剂。显微红外非常适合分析微量有机物。Py-GC/MS在分析样品时无需对样品进行前处理，可直接对样品进行热裂解分析；该方法操作比较简单、灵敏度高、能实现多组分混合有机样品识别，非常适合用于评价文物上的混合有机材料。该工作既能为铁器上文物保护修复材料的现状提供科学评价方法，也为评价过去使用过的保护修复方法、铁器的长久保存提供重要的指导。

At the beginning of 1970s, conservators at National Museum of China started research on the protection and restoration of ironware. According to the degree of rust, the cultural relics protection and restoration personnel carried out cleaning, rust removal, desalination, bonding and sealing treatments. When examining and reviewing the four iron wares that were protected and restored at that time for fully understanding the previous restorations done on these iron wares, the work uses Fourier Transform Infrared Spectroscopy (FTIR) and Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC/MS) to analyze the restoration materials used in the collection of ironware. Py-GC/MS does not require sample pretreatment when analyzing samples, and the samples can be directly analyzed by thermal cracking, and the operation is relatively simple. In addition, this method requires a small amount of sample. It can not only provide a scientific evaluation the repair materials in iron wares, but also provide important guidance for evaluating the protection and restoration methods used in the past and the long-term preservation of iron wares.
